2940 Air Adjust Installation Guide Outline
STEP 1: RESIDUE MANAGER (RM) OR RM/COULTER COMBO INSTALLATION
Residue Manager Only: Install the RM Assembly using mounting hardware. When installing wheel mount assembly on the adjustment tube of
th
th
the RM Assembly, place the top hole of the wheel mount to the 4
or 5
hole from the top of the adjustment tube for conventional tillage or mellow
th
th
soils, 5
or 6
hole from the top for no/minimum till conditions. Install wheels on wheel mounts using hardware from the 2966-119 bolt bag. Install
the RM wheels so that the left wheel leads, right wheel trails on the left side of the planter & the right wheel leads, left wheel trails on the right side.
RM/ Coulter Combo: Install the RM/Coulter Combo assembly using hardware from the 2940-128 bolt bag. Mount the coulter blade on the coulter
arm hub & mount the RM wheels using the 5/8 Whiz Lock Nuts. RM wheels on combo units will install in the rear holes on both sides on all rows. It
is recommended to set the coulter blade equal to or above seed depth. Refer to the diagrams on pages 16 - 19
STEP 2: INSTALLING 2940-100 CAB CONTROLLER
Mount the 2940-100 Cab Controller & 2940-113 RAM Mount in the tractor cab. Position the Cab Controller within reach during operation without
compromising safety/visibility from the cab. Connect the 2940-152 harness to the female 6 pin connector on the back of the cab controller & route
the black CAN connector towards the hitch of the tractor. Connect the 2940-153 2 pin connector to the female 2 pin connector on the back cab
controller. Splice the red & black wires to the appropriate connector to fit the tractor's switched power source.
Refer to the diagram on page 20
STEP 3: INSTALLING COMPRESSOR ASSEMBLY & POWER CABLES
COMPRESSOR: Begin by locating a suitable mounting location for the compressor assembly. Placement of the compressor assembly will vary on
the make and model of the planter. Use mounts supplied or depending on application, different mounts may need to be built. NOTE: Be sure to
check clearance of compressor assembly in all locations, especially noting tractor tires during turns, folding/unfolding the planter for transport
mode, markers, and 2-point top link. The compressor must be mounted using 50 feet or less of main power cable extensions from the operating
tractor's battery. If over 50 feet, heavier gauge power cables (00) must be built or purchased in the correct length.
POWER CABLE: Install the 2940-150 main power cable with 80amp breaker on the battery terminals (red is positive+, black is negative -). Next,
connect the appropriate length of main power extensions (2940-151 or 2940-163) off of the 2940-150, route the main power extensions to large
Anderson power connector coming out of the 2940-101A compressor assembly housing, & install. Install the 2940-181 Y harness on the
compressor. Refer to the diagram on pages 21 & 23
STEP 4: CONTROL BOX AND HARNESS INSTALLATION
CONTROL BOX: Mount the control box in a safe location with mounts/hardware supplied. Install the 2940-415 water separator/regulator assembly
near the control box. Measure & cut the 2940-367 250psi rated 3/8" airline, install airline from outlet elbow on compressor into the 2940-415 inlet
(water trap side). The regulator is preset to only allow 100psi of clean, dry air beyond it. Install 2940-345 3/8" airline from the 2940-415 outlet
(regulator side) to control box inlet. Install ¼" airline from the elbow on the bottom of the 2940-415 to the ¼"PTC fitting closest to the door hinge on
the side of the control box. Route ¼" airline from remaining ¼"PTC fitting on the 2940-103 toward the ground, as airline will dispense moisture.
HARNESS: Install the 2940-166 VDM power cable with 40amp breaker on the battery terminals (red is positive+, black is negative -). Install the
appropriate length VDM power extension (2940-167 or 2940-168) off of the 2940-166, route to the hitch of the tractor to install into the matching
connector on the CAN AUX to Air Harness. Lastly, install the CAN AUX to Air Harness, 2940-164 (5ft) or 2940-165 (10ft). The smaller Anderson
power connector will connect to the VDM power extension, the black CAN connector connects to the other black CAN connector that routes to the
cab controller, & the black male 12 pin Deutsch connector connects to the black female end on the side of the control box housing. 2940-170
(10ft), 2940-171 (30ft), or 2940-430 (20ft) CAN AUX to Air Extensions may be necessary if the control box is mounted further back on the planter
than the hitch. Install the compressor communication harness, 2940-182 or 2940-189 into the 4 pin connector on the control box and route to the
compressor and install into the 2940-181 Y harness. Refer to the diagram on page 22 - 24
STEP 5: DUMP VALVE & DUMP VALVE HARNESS INSTALLATION
Install the dump valves (DV) to the planter as shown in the diagram that matches your planter. 16 row planters and less will have 1 up pressure &
1 down pressure DV on the middle of each wing/side & 1 up pressure & 1 down pressure DV on the wheel track (WT) or center rows. 24 row
planters & larger will have 3 DVs per wing/side; 2 down pressure & 1 up pressure, & 2 DVs on the WT rows, 1 up pressure & 1 down pressure.
Install the gray male 12 pin Deutsch connector of the 2940-162 into the gray female 12 pin Deutsch on the bottom side of the compressor
assembly housing. The 2940-162 will have 4) 2 pin pig tails. The connector labeled RM Up Dump (yellow/black wires) will connect to all up
pressure DVs using 2940-155 (30ft), 2940-157 (15ft), & 2940-160 (5ft) white DV harnesses. Use 2940-159 white Y harnesses to connect all white
DV cables together. The connector labeled RM Down Dump (orange/black wires) will connect to all down pressure DVs using 2940-154 (30ft),
2940-156 (15ft), 2940-161 (5ft) black dump valve harnesses. Use 2940-158 black Y harnesses to connect all black DV cables together.
CONNECTORS LABELED AUX 3 & AUX 4 WILL NOT BE USED! Refer to pages 24 - 36
STEP 6: PLUMBING AIRLINES
A group of airlines that route to the residue manager air bags are referred to as trunk airlines. The airline routing from the RU, RD, & WT to the
inlet of the DV for the matching circuit is referred to as a supply airline. Start by routing the trunk airlines: route black (down pressure) & blue (up
pressure) airline on each wing/side of the planter. If installing on a split row planter, keep the airline on the front rank residue managers on each
wing plumbed separate from the back rank. When plumbing in the WT (wheel track) rows, use the center 4 or 6 rows that plant over the tractor &
planter wheel tracks. If equipping on a narrow transport planter with 4 center rows & 6 rows are desired on the WT circuit, tie in the 1 row on each
wing/side of the planter closest to the first & last center row. Use supplied tees to make enough open ports in each circuit to install supply airline to
the inlet port of each DV of the matching circuit. Also use tees to connect the outlet port of the DVs to the matching circuits of the trunk airlines. On
split row planters, a ball valve will be used to shut air off to bean rows when planting corn. Refer to the diagrams on pages 25 - 37
STEP 7: PERFORM A PRE-OPERATIOIN TEST OF THE SYSTEM
Now that the system is installed, perform a pre-operation test. Start by folding/unfolding & lowering/raising the planter to check for enough slack in
airline & in harnesses at hinge points. Check all electrical connections, cables, & airline making sure nothing was damaged. Next, turn on the cab
controller by holding the power button. After the cab controller is on, turn all pressures (RU, RD, and WT) to 0psi & press ENTER to activate the
system. The compressor will turn on, build to 95psi & turn off. Check the interior of the compressor housing (PQE, Pressure on Valve, & airline
within the housing) for leaks. Apply 30psi to the RU port & watch your row cleaners as they should all rise to maximum up travel. Check for leaks
on all up pressure circuits & fittings. When that leak check is finished, turn RU to 0psi & turn RD & WT to 30. Check all down pressure airline &
fittings in these circuits for leaks & repair as needed. Refer to page 42 - 44
